Vulnerability Overview

The Plethora Plugins Tabs + Accordions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the anchor parameter in all versions up to, and including, 1.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-85: Doubled Character XSS Manipulations

The web application does not filter user-controlled input for executable script disguised using doubling of the involved characters.

Remediation

Update to version 1.2, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Plethora Tabs + Accordions 1.2 closes this, and updating the plugin is the step that ends it.
